Add a alloc_pages_exact_nid() that allocates on a specific node.
The naming is quite broken, but fixing that would need a larger
renaming action.

From: Andi Kleen <ak@linux.intel.com>
dde79e005a769 added a regression that the memory cgroup data structures
all end up in node 0 because the first attempt at allocating them
would not pass in a node hint. Since the initialization runs on CPU #0
it would all end up node 0. This is a problem on large memory systems,
where node 0 would lose a lot of memory.
Change the alloc_pages_exact to alloc_pages_exact_node. This will
still fall back to other nodes if not enough memory is available.
[RED-PEN: right now it would fall back first before trying
vmalloc_node. Probably not the best strategy ... But I left it like
that for now.]
v4: Remove debugging code.
v3: Really call the correct function now. Thanks for everyone who commented.

This conflicts in, I suspect, a more-than-textual manner with Dave's
http://userweb.kernel.org/~akpm/mmotm/broken-out/mm-make-new-alloc_pages_exact.patch
Can you please take a look at that and work out what we should do?
As your [patch 2/2] fixes a regression, the answer might be "drop
Dave's patch".

It should be relatively simple to rebase Dave's patch on top of mine.
I think that's the right order: first regression fix, then cleanup.
Sorry Dave for the additional work.
(I agree the cleanup is very valuable in itself)

I started repairing Dave's stuff but then things got complex. Probably
we should rename your new alloc_pages_exact_nid() to
get_free_pages_exact_nid().
